If they really did want an idilic life with no ties and the ability to up-sitcks and go whenever they felt like it there would be a great deal of romance for their lifestyle.
The reality is they leave a right disgusting mess wherever they have been and expect tax payers to foot the bill to clean it up.
I pass a tiny patch of grass on the way home from work every night and every couple of months they forcefully remove the fencing to take over the area, and when they move on the whole area looks like the aftermath of a riot. Currently there is a mattress hanging over the fence, rubbish everywhere, a gas canister and an abandoned caravan.
I'd love to be a free spirit and not have to pay the government something every mouth, but I am certain that in return I would clean up after myself.
